Does OX4 flood?

Yes — parts of the OX4 district carry real flood risk: 41 of its 117 at-risk postcodes reach the Environment Agency's High likelihood band. The OX4 postcode district covers Blackbird Leys, Donnington, St Mary's, Northfield Brook, close to Kennington, South Hinksey, Sandford-on-Thames, and surrounding villages in Oxfordshire.

117 postcodes in the OX4 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 41 high, 17 medium, 59 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
